一个这样的url 如何让编码让他显示成类型下面这样
https://forum.csdn.net/$%23$%#$%@#34$%#.asp

加解密的吧，这样不利于seo啊

[sheng9hhd]

类似UrlRewriter,写在httpmodule里面

[编程有钱人了]

<a href=index.aspx?id=Server.UrlDecode(<%#Eval("id")%>)></a>
<!-- 或者-->
https://forum.csdn.net/Server.UrlDecode(<%#Eval("name")%>.aspx

解码和编码有什么区别 解码是不是还是原来的网址 没有变化啊？

string url = "/Lessons/Dialogue.aspx?lId=179&id=root_1_35_0";

this.Response.Redirect(Server.UrlEncode(url));
我这样写 页面会出现 错误 "HTTP 閿欒 400 - Bad Request銆?/i> "

用字符串加密就可以了

[billclinton8]

对了 忘了说了 加密后 在编码 有可能加密后有些字符在URL要遍

字符串怎么加密啊？
